Description

Technical Field

[0001] The present invention relates to the technical field of organic waste gas treatment, and in particular to a multi-stage circulation organic waste gas treatment device and a method thereof. Background Art

[0002] Organic waste gas treatment refers to the process of adsorbing, filtering and purifying waste gas containing organic substances such as carbon, hydrogen and oxygen generated in the industrial production process. These waste gases mainly come from electronic devices, chemical plants, petrochemical equipment, architectural coatings, packaging printing, spraying, furniture, leather products and other fields. Since organic waste gas is generally flammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to treat, it needs to be treated by special methods.

[0003] In the prior art, a Chinese patent with publication number CN117443135B is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a multi-stage circulating organic waste gas treatment device, including an air inlet pipe, a dust removal mechanism, a connecting pipe, an adsorption and desorption mechanism, a connecting pipe, a catalytic combustion mechanism, an air outlet pipe, a supporting leg, and a hot air pipe; the air inlet pipe is connected to one side of the dust removal mechanism, the catalytic combustion mechanism is located on one side of the dust removal mechanism, and the adsorption and desorption mechanism is fixed on the top of the catalytic combustion mechanism; the connecting pipe connects the dust removal mechanism and the adsorption and desorption mechanism, and the connecting pipe connects the adsorption and desorption mechanism and the catalytic combustion mechanism; the air outlet pipe is connected to the adsorption and desorption mechanism, and a detection box and a reflux pipe are provided on the air outlet pipe; the hot air pipe is connected to the bottom of the catalytic combustion mechanism; and the supporting leg is fixed to the bottom of the adsorption and desorption mechanism. The present invention can perform multi-layer spray dust removal on waste gas, ensure uninterrupted treatment of organic waste gas during the adsorption and desorption process of organic waste gas by activated carbon, improve the catalytic combustion efficiency of waste gas, and make the treatment of organic waste gas more thorough. However, in the subsequent waste gas treatment process, it is necessary to separate the organic waste gas, and then separate a small amount of polluted waste gas for centralized treatment to meet the standards. In this process, the gas separation membrane may age or fail due to long-term operation, which will lead to a decrease or interruption in the waste gas treatment efficiency, necessitating shutdown for treatment. Summary of the invention

[0004] The object of the present invention is to provide a multi-stage circulation organic waste gas treatment device and method thereof, so as to solve the problem in the above-mentioned background technology that the working efficiency of the waste gas treatment device is reduced or interrupted due to aging or failure of the membrane.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A multi-stage circulating organic waste gas treatment device comprises a waste gas impurity removal device for removing impurities from the organic waste gas; a liquid injection screw compressor device for compressing the organic waste gas, a gas-liquid separation device for gas-liquid separation of the organic waste gas, a condensation device for condensing the separated organic waste gas and a gas separation component for separating non-condensable gas are sequentially distributed in a zigzag shape on one side of the waste gas impurity removal device, which are sequentially connected end to end, and one end of the gas separation component is fixedly connected to the input end of the liquid injection screw compressor device to form a closed loop, and the organic waste gas is treated multiple times in multiple stages; a liquid storage tank is provided on one side of the condensation device, and the liquid storage tank and the condensation device are connected to each other; the gas separation component comprises a separation tank, two separation tanks are symmetrically arranged, a support seat for supporting the separation tank is fixedly installed at the bottom end of the separation tank, the two separation tanks are fixedly connected by connecting pieces symmetrically arranged up and down, a discharge pipe is fixedly installed at the bottom end of the separation tank, a mounting frame is provided between the two separation tanks, and the two sides of the mounting frame are respectively fixedly connected to one side of the two connecting pieces, a guide rod is fixedly installed symmetrically up and down on the inner side of the mounting frame, and a sliding plate is slidably connected between the two guide rods.

[0007] By adopting the above technical scheme, when it is necessary to perform multi-stage treatment on the organic waste gas, the organic waste gas to be treated is first passed through the waste gas impurity removal device to clean the impurities in the waste gas, and then the impurity-removed waste gas is transported to the inside of the liquid injection screw compressor device, and the waste gas is compressed by the liquid injection screw compressor device to increase the pressure to 0.8MPa, and the compressed waste gas is transported to the gas-liquid separation device to separate most of the condensed circulating liquid from the waste gas. Then, the waste gas enters the condensation device for condensation, and a large amount of gas in the waste gas is condensed into liquid and enters the liquid storage tank, while the non-condensable waste gas enters the inside of the gas separation component for gas separation, and most of the non-condensable gas passes through the gas separation membrane, and enters the input port of the gas-liquid separation device after enrichment and concentration, and the compression and condensation process is performed again, and the gas that has not passed through still contains a small amount of polluting waste gas, which will enter the terminal equipment through the discharge pipe for standard treatment, and the multi-stage closed-loop circulation treatment mechanism can quickly treat the organic waste gas so that it can meet the emission standards.

[0008] A further improvement of the technical solution of the present invention is that the gas separation component also includes a connecting block, the two connecting blocks are symmetrically fixedly installed at the two ends of the sliding plate, the two connecting blocks are fixedly installed with mounting blocks at one end away from the sliding plate, and a connecting rod is fixedly installed at one end of the mounting block away from the connecting block, and limiting rods are symmetrically provided on both sides of the connecting rod, one end of the two limiting rods is fixedly connected to one end of the sliding plate, and the two limiting rods pass through the side wall of the mounting frame at one end away from the sliding plate, the inside of the mounting block is symmetrically slidably connected with a limiting seat, one end of the two limiting seats is rotatably connected with a conduction block, the two conduction blocks are rotatably connected with a connecting seat at one end away from the limiting seat, the inside of the connecting rod is rotatably connected with a sliding rod, one end of the sliding rod is fixedly connected to one end of the connecting seat, the end of the connecting rod away from the connecting block is slidably connected with a handle, and a limiting component is fixedly installed at one end of the mounting frame.

[0009] By adopting the above technical solution, when the gas separation component needs to be replaced, the operating steps are as follows: first, the staff will use the handle to rotate the connecting rod. As the connecting rod rotates, a limiting component will be activated, thereby releasing the current position limit of the connecting rod. Then, the staff will pull the sliding rod through the handle again to make it slide along the end of the connecting rod. The sliding rod drives the conduction block to move synchronously through the connecting seat. The movement of the conduction block then prompts the two limiting seats to approach each other. This action releases the original position lock of the sliding plate. Once the position limit of the sliding plate is released, the staff can pull the sliding plate through the handle and the connecting rod to make it slide smoothly along the guide rod to the other end of the mounting frame. After reaching the specified position, use the handle at the other end of the mounting frame to rotate the connecting rod again, and re-fix the position of the connecting rod and the sliding plate through the limiting component to ensure that the sliding plate is stable and motionless. Finally, the staff can easily replace the gas separation structure installed on the sliding plate. The whole process realizes the rapid and safe replacement of the gas separation component.

[0010] A further improvement of the technical solution of the present invention is that: an inner ring of the mounting frame is provided with a receiving groove that cooperates with the sliding plate, and both ends of the mounting frame are provided with lightweight grooves.

[0011] By adopting the above technical solution, a accommodating groove is designed in the interior of the mounting frame using the spatial layout. When one end of the sliding plate is completely pulled to the end of the mounting frame, the accommodating groove can provide a hidden storage space and automatically physically restrict the sliding plate to ensure that it is stable and immobile. This additional restriction mechanism not only enhances the stability of the sliding plate during use, but also makes the entire system more compact and orderly, which brings great convenience to the staff's operation. Through such a design, the staff can manage and maintain the gas separation components more easily and efficiently, thereby improving the overall work efficiency and user experience.

[0012] A further improvement of the technical solution of the present invention is that: the limiting component includes a matching seat, the two matching seats are respectively fixedly mounted on the two ends of the mounting frame, the matching seat is internally slidably connected with a connecting plate, one end of the connecting plate is fixedly connected to one end of an auxiliary spring, and the auxiliary spring is arranged inside the matching seat, a limiting block is symmetrically fixedly mounted on the outer wall of one end of the connecting rod close to the handle, and a matching groove is provided at one end of the matching seat close to the handle for clamping with the limiting block.

[0013] By adopting the above technical solution, when it is necessary to operate the sliding plate to move, the staff can use the handle to rotate the connecting rod. As the connecting rod rotates, the limiting block installed on it will rotate along the preset matching groove trajectory in the matching seat. This process allows the limiting block to smoothly disengage from the matching seat, thereby allowing the sliding plate to move freely. When the sliding plate reaches the predetermined position at the other end of the mounting frame, the limiting block on the connecting rod at this end of the sliding plate is just inserted into the corresponding matching groove. At this time, the limiting block will squeeze the connecting plate, thereby compressing the auxiliary spring to generate a certain preload force. Subsequently, the connecting rod is rotated again by the handle to make the limiting block completely rotate into the matching groove, thereby achieving a firm locking between the connecting rod and the mounting frame. This design significantly enhances the stability and safety of the device during use.

[0014] A further improvement of the technical solution of the present invention is that: a first limiting seat that is snap-fitted with the limiting seat is symmetrically fixedly installed on both sides of the separation tank, and a second limiting seat that is snap-fitted with the limiting seat is symmetrically fixedly installed on both sides of the end of the mounting frame, and the ends of the first limiting seat and the second limiting seat are both provided with matching grooves that are snap-fitted with the limiting seat.

[0015] By adopting the above technical solution, a first limiting seat and a second limiting seat are installed at the corresponding positions of the separation tank and the mounting frame respectively. These two limiting seats work together to accurately control and stably limit the displacement of the sliding plate. Such a design not only enhances the stability of the equipment during operation, but also greatly improves the convenience of operation, allowing staff to use the device more easily and efficiently.

[0016] A further improvement of the technical solution of the present invention is that the handle and the limiting block are arranged vertically, and the two conducting blocks are arranged in an eight-shaped shape, showing a staggered arrangement in the up-and-down direction.

[0017] By adopting the above technical solution, the vertical layout of the handle and the limiting block design greatly facilitates the staff to rotate the connecting rod, so that the limiting block can be quickly and stably embedded in the corresponding matching groove, thereby effectively locking the position of the connecting rod and enhancing the accuracy of the operation and the stability of the device. In addition, by designing the conduction blocks in an upper and lower staggered arrangement, not only the installation space required between the two conduction blocks is significantly reduced, effectively reducing the total volume of the device, but also the connection stability and tacit cooperation between the two are significantly improved, ensuring smoother and more efficient operation of the device.

[0018] A further improvement of the technical solution of the present invention is that a gas separation structure is installed at both ends of the sliding plate, and the gas separation structure includes a connecting air pipe, which is symmetrically fixedly installed at both ends of the sliding plate, and circular mounting grooves are provided at both ends of the sliding plate. Extrusion rings are slidably connected in the circular mounting grooves at both ends of the sliding plate, and the outer rings of the two extrusion rings are sleeved with sealing rings, and the inner ring of the extrusion ring is provided with an installation ring, which is fixedly connected to the extrusion ring by a number of connecting bolts, and the number of connecting bolts are distributed in a ring shape on the installation ring, and a gas separation membrane is fixedly installed on the installation ring.

[0019] By adopting the above technical scheme, when the gas separation membrane needs to be replaced, the staff uses the coordinated work of the hydraulic device and the connecting air pipe to extract the hydraulic oil in the circular mounting groove in the sliding plate. This operation makes the extrusion ring no longer close to the side wall of the separation tank, thereby allowing the sliding plate to move freely. To ensure the sealing, a sealing ring is installed on the periphery of the extrusion ring. As the sliding plate moves, the old gas separation membrane is extracted from the separation tank, and the new gas separation membrane is pushed in. Subsequently, hydraulic oil is injected into the circular mounting groove corresponding to the new gas separation membrane through the hydraulic device and the connecting air pipe again. The pressure of the hydraulic oil makes the extrusion ring fit tightly against the side wall of the separation tank, thereby enhancing the sealing effect and ensuring the efficient treatment of the exhaust gas. For the used gas separation membrane, the staff can easily remove the connecting bolts on its outer edge, and then separate the mounting ring from the extrusion ring, thereby realizing the convenient replacement of the gas separation membrane. This alternating working mechanism not only shortens the downtime of the device, allowing it to quickly return to the exhaust gas treatment process, but also greatly facilitates the maintenance operations of the staff and improves the overall work efficiency.

[0020] A further improvement of the technical solution of the present invention is that an observation component is fixedly installed on the top of the separation tank, the observation component includes a fixed seat, the fixed seat is fixedly installed on the top of the separation tank, an industrial camera is fixedly installed on the bottom of the fixed seat, and the end of the industrial camera extends to the interior of the separation tank, a display screen is fixedly installed on the top of the fixed seat, and the industrial camera and the display screen are electrically connected.

[0021] By adopting the above technical solution, in order to monitor the working status of the gas separation membrane in the separation tank in real time, an industrial camera is installed inside the separation tank, which can capture and feedback the detailed status of the gas separation membrane in real time to ensure the timeliness of information. In order to improve the intuitiveness of the operation, the industrial camera is closely connected to the display screen. The staff only needs to observe the display screen to understand the real-time usage of the gas separation membrane at a glance. Based on this real-time information, the staff can quickly determine whether the gas separation membrane needs to be replaced, thereby ensuring the continuity and efficiency of the exhaust gas treatment process.

[0022] A further improvement of the technical solution of the present invention is that the angle between the industrial camera and the gas separation membrane is set at 110°.

[0023] Using the above technical solution, the industrial camera is installed at an angle of 110° to the gas separation membrane, ensuring that the industrial camera can capture the details of the gas separation membrane with the widest field of view. Through such a layout, the industrial camera can capture the overall picture of the gas separation membrane and its working status to the greatest extent, and then transmit the real-time image to the display screen. The staff only needs to directly observe the picture on the display screen to intuitively evaluate the current condition of the gas separation membrane, so as to quickly and accurately determine whether replacement operation is needed. This design not only improves the monitoring efficiency, but also greatly facilitates the maintenance and management of the equipment.

[0024] The present invention also provides a treatment method of a multi-stage circulating organic waste gas treatment device, comprising:

[0025] S1. Waste gas treatment, transporting the organic waste gas to be treated to the inside of the waste gas impurity removal device, cleaning the impurities inside the organic waste gas through the waste gas impurity removal device, and then transporting the impurity-free waste gas to the liquid injection screw compressor device, and compressing the waste gas through the liquid injection screw compressor device;

[0026] S2, gas treatment, the compressed waste gas is transported to the gas-liquid separation device to separate most of the condensed circulating liquid from the waste gas, and then the waste gas enters the condensing device for condensation. A large amount of gas in the waste gas is condensed into liquid and enters the liquid storage tank, while the non-condensable waste gas enters the interior of the gas separation component;

[0027] S3, gas separation, the non-condensable waste gas is transported to the gas separation component, and the gas is separated by the gas separation membrane. The non-condensable gas that passes through the gas separation membrane will be enriched and concentrated and then enter the input port of the gas-liquid separation device for gas treatment again. The gas that does not pass through still contains a small amount of polluted waste gas, which will be sent to the terminal equipment for treatment to meet the standards.

[0028] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0029] 1. The present invention optimizes the replacement process of the gas separation membrane through the double-station design of the sliding plate, which not only greatly shortens the equipment downtime due to the replacement of the gas separation membrane, but also ensures the continuity and efficiency of the exhaust gas treatment process. At the same time, when one station is in working condition, the other idle station provides sufficient space for the operator, so that the used gas separation membrane can be easily and quickly replaced without worrying about the limited operating space. In addition, the double-station configuration also gives the work higher flexibility, allowing the staff to flexibly arrange the replacement time of the gas separation membrane according to actual needs, further improving the efficiency and convenience of the overall operation.

[0030] 2. In the present invention, limiting structures are provided at both ends of the sliding plate, which can quickly and accurately position the sliding plate and realize seamless switching between the double working positions of the sliding plate. This limiting structure cleverly uses the mechanical transmission mechanism, which not only ensures the high efficiency and stability of the transmission process, but also is particularly suitable for sliding plates that frequently change positions due to the inherent advantages of mechanical transmission - easy maintenance, low cost, and low failure rate, thereby improving the stability and efficiency of the overall device during operation. In addition, the mounting frame can accurately limit the moving range of the sliding plate and the trajectory of the double-working position switching, which not only optimizes the moving path of the sliding plate between the double working positions, but also enhances its matching degree with the separation tank, ensuring that each switching can achieve a high degree of accuracy and efficiency. Therefore, when the entire device is in operation, it exhibits excellent performance in terms of switching speed and operating accuracy, greatly improving work efficiency and convenience of use.

[0031] 3. The liquid-injecting screw compressor device, gas-liquid separation device, condensing device and gas separation component in the present invention jointly construct an efficient closed-loop treatment system. The system significantly accelerates the treatment process of organic waste gas through a multi-stage and multi-cycle treatment process. This mechanism not only enhances the device's ability to treat organic waste gas, but also effectively improves the treatment effect, ensuring that the waste gas can quickly meet the established emission standards after treatment, thereby achieving the goal of both environmental protection and high efficiency.

[0032] 4. In order to realize real-time monitoring and evaluation of the use status of the gas separation membrane in the present invention, an observation component is installed on the separation tank. The industrial camera in the observation component can capture and record the detailed working status of the gas separation membrane in real time with high precision. These real-time images are then intuitively displayed through the display screen, providing the operator with a clear and real-time monitoring window, so that the current status of the gas separation membrane is clear at a glance. Based on this efficient observation system, the staff can quickly and accurately determine whether the gas separation membrane needs to be replaced. Once it is found that the performance of the membrane has declined or reached the replacement standard, action can be taken immediately to effectively avoid the decline or interruption of treatment efficiency due to aging or failure of the membrane. This instant response mechanism ensures the continuity and efficiency of the waste gas treatment process, while also improving the operating stability and reliability of the overall equipment, so that the treatment of organic waste gas is always maintained in the optimal state.

[0033] 5. In order to optimize the collaborative working efficiency between the separation tanks in the present invention, the double-station design of the sliding plate is provided with a gas separation structure. This layout ensures that when one end of the sliding plate is in working condition, its corresponding gas separation structure can effectively maintain airtightness and strictly prevent gas leakage, thereby ensuring the stability and continuity of the gas separation process. In addition, the driving mechanism of the extrusion ring adopts a hydraulic drive method. This choice enables the extrusion ring to achieve a high uniformity of the contact surface when it contacts and extrude the separation tank, significantly improving the airtightness of the entire device. The hydraulic drive not only has a stable and controllable force, but also can effectively reduce the impact and wear during the contact process, further extending the service life of the equipment. This design improvement greatly facilitates the device's treatment process of exhaust gas and ensures the efficiency and stability of the treatment effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The present invention is further described in detail below in conjunction with embodiments:

[0047] Example 1

[0048] like Figure 1-Figure 10 As shown, the present invention provides a multi-stage circulating organic waste gas treatment device, comprising:

[0049] The waste gas impurity removal device 1 is used to remove impurities from the organic waste gas; one side of the waste gas impurity removal device 1 is sequentially distributed in a zigzag shape with a liquid injection screw compressor device 2 for compressing the organic waste gas, a gas-liquid separation device 3 for gas-liquid separation of the organic waste gas, a condensation device 4 for condensing the separated organic waste gas, and a gas separation component 6 for separating the non-condensable gas, which are sequentially connected end to end, and one end of the gas separation component 6 is fixedly connected to the input end of the liquid injection screw compressor device 2 to form a closed loop, and the organic waste gas is processed in multiple stages and multiple times. A liquid storage tank 5 is provided on one side of the condensation device 4, and the storage tank 5 is provided. The liquid tank 5 is connected to the condensing device 4; the gas separation assembly 6 includes a separation tank 7, and the two separation tanks 7 are symmetrically arranged. A support seat 8 for supporting the separation tank 7 is fixedly installed at the bottom of the separation tank 7, and the two separation tanks 7 are fixedly connected by a connecting piece 9 symmetrically arranged up and down. A discharge pipe 10 is fixedly installed at the bottom of the separation tank 7, and a mounting frame 11 is provided between the two separation tanks 7, and both sides of the mounting frame 11 are respectively fixedly connected to one side of the two connecting pieces 9, and guide rods 12 are symmetrically fixedly installed on the inner side of the mounting frame 11, and a sliding plate 13 is slidably connected between the two guide rods 12.

[0050] In this embodiment, when it is necessary to perform multi-stage treatment on the organic waste gas, the organic waste gas to be treated is firstly passed through the waste gas impurity removal device 1 to clean the impurities in the waste gas, and then the impurity-removed waste gas is transported to the inside of the liquid injection screw compressor device 2, and the waste gas is compressed by the liquid injection screw compressor device 2 to increase the pressure to 0.8MPaG, and the compressed waste gas is transported to the gas-liquid separation device 3 to separate most of the condensed circulating liquid from the waste gas, and then the waste gas enters the condensing device 4 for condensation, and a large amount of gas in the waste gas is The non-condensable waste gas is condensed into liquid and enters the liquid storage tank 5, while the non-condensable waste gas enters the interior of the gas separation component 6 for gas separation. Most of the non-condensable gas passes through the gas separation membrane 35, and enters the input port of the gas-liquid separation device 3 after enrichment and concentration, and is compressed and condensed again. The gas that has not passed through still contains a small amount of polluting waste gas. This part of the gas will enter the terminal equipment through the discharge pipe 10 for standard treatment. The multi-stage closed-loop circulation treatment mechanism can quickly treat the organic waste gas so that it can meet the emission standards.

[0051] Example 2

[0052] like Figure 3-Figure 9As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the gas separation component 6 also includes a connecting block 14, two connecting blocks 14 are symmetrically fixedly installed at both ends of the sliding plate 13, the ends of the two connecting blocks 14 away from the sliding plate 13 are fixedly installed with a mounting block 17, and the end of the mounting block 17 away from the connecting block 14 is fixedly installed with a connecting rod 15, and both sides of the connecting rod 15 are symmetrically provided with limiting rods 16 on the upper and lower sides, one end of the two limiting rods 16 is fixedly connected to one end of the sliding plate 13, and the ends of the two limiting rods 16 away from the sliding plate 13 pass through the side wall of the mounting frame 11, the interior of the mounting block 17 is symmetrically slidably connected with a limiting seat 18, one end of the two limiting seats 18 is rotatably connected with a conduction block 19, and the ends of the two conduction blocks 19 away from the limit seat 18 are rotatably connected with a connecting seat 21, the interior of the connecting rod 15 is rotatably connected with a sliding rod 20, one end of the sliding rod 20 is fixedly connected to one end of the connecting seat 21, the end of the connecting rod 15 away from the connecting block 14 is slidably connected with a handle 22, and a limiting component is fixedly installed at one end of the mounting frame 11.

[0053] In this embodiment, when the gas separation component 6 needs to be replaced, the operation steps are as follows: first, the staff will use the handle 22 to rotate the connecting rod 15. As the connecting rod 15 rotates, a limiting component will be activated, thereby releasing the current position limit of the connecting rod 15. Then, the staff will pull the sliding rod 20 again through the handle 22 to make it slide along the end of the connecting rod 15. The sliding rod 20 drives the conductive block 19 to move synchronously through the connecting seat 21. The movement of the conductive block 19 then causes the two limiting seats 18 to approach each other. This action releases the original position lock of the sliding plate 13. Once the position restriction of the sliding plate 13 is released, the staff can pull the sliding plate 13 through the handle 22 and the connecting rod 15, so that it can slide smoothly along the guide rod 12 to the other end of the mounting frame 11. After reaching the specified position, the connecting rod 15 is rotated again using the handle 22 at the other end of the mounting frame 11, and the position of the connecting rod 15 and the sliding plate 13 is re-fixed through the restriction assembly to ensure that the sliding plate 13 is stable and immovable. Finally, the staff can easily replace the gas separation structure installed on the sliding plate 13. The whole process realizes the rapid and safe replacement of the gas separation assembly 6.

[0054] like Figure 6 and Figure 7 As shown, in this embodiment, preferably, the inner circle of the mounting frame 11 is provided with a receiving groove that cooperates with the sliding plate 13, and both ends of the mounting frame 11 are provided with lightweight grooves.

[0055] In this embodiment, a receiving groove is designed in the interior of the mounting frame 11 by utilizing the spatial layout. When one end of the sliding plate 13 is completely pulled to the end of the mounting frame 11, the receiving groove can provide a hidden storage space and automatically physically restrict the sliding plate 13 to ensure that it is stable and immobile. This additional restriction mechanism not only enhances the stability of the sliding plate 13 during use, but also makes the entire system more compact and orderly, which greatly facilitates the operation of the staff. Through such a design, the staff can manage and maintain the gas separation assembly 6 more easily and efficiently, thereby improving the overall work efficiency and user experience.

[0056] like Figure 6 and Figure 7 As shown, in the present embodiment, preferably, the limiting assembly includes a mating seat 23, and the two mating seats 23 are respectively fixedly mounted at the two ends of the mounting frame 11, and the interior of the mating seat 23 is slidably connected with a connecting piece 24, one end of the connecting piece 24 is fixedly connected to one end of an auxiliary spring 25, and the auxiliary spring 25 is arranged inside the mating seat 23, and a limiting block 26 is symmetrically fixedly mounted on the outer wall of one end of the connecting rod 15 close to the handle 22, and a mating groove 27 which is snap-fitted with the limiting block 26 is opened at one end of the mating seat 23 close to the handle 22.

[0057] In this embodiment, when it is necessary to operate the sliding plate 13 to move, the staff can use the handle 22 to rotate the connecting rod 15. As the connecting rod 15 rotates, the limiting block 26 installed thereon will rotate along the trajectory of the preset matching groove 27 in the matching seat 23. This process allows the limiting block 26 to be smoothly disengaged from the matching seat 23, thereby allowing the sliding plate 13 to move freely. When the sliding plate 13 reaches the predetermined position at the other end of the mounting frame 11, and the limiting block 26 on the connecting rod 15 at this end of the sliding plate 13 is just inserted into the corresponding matching groove 27, at this time, the limiting block 26 will squeeze the connecting piece 24, thereby compressing the auxiliary spring 25 to generate a certain pre-tightening force, and then, the connecting rod 15 is rotated again by the handle 22, so that the limiting block 26 is completely rotated into the matching groove 27, thereby realizing the firm locking between the connecting rod 15 and the mounting frame 11. This design significantly enhances the stability and safety of the device during use.

[0058] like Figure 4 As shown, preferably, the first limiting seats 28 that are snap-fitted with the limiting seats 18 are symmetrically fixedly installed on both sides of the separation tank 7, and the second limiting seats 29 that are snap-fitted with the limiting seats 18 are symmetrically fixedly installed on both sides of the end of the mounting frame 11, and the ends of the first limiting seat 28 and the second limiting seat 29 are both provided with matching grooves that are snap-fitted with the limiting seat 18.

[0059] In this embodiment, a first limiting seat 28 and a second limiting seat 29 are respectively installed at corresponding positions of the separation tank 7 and the mounting frame 11. These two limiting seats work together with the limiting seat 18 to precisely control and stably limit the displacement of the sliding plate 13. Such a design not only enhances the stability of the equipment during operation, but also greatly improves the convenience of operation, allowing staff to use the device more easily and efficiently.

[0060] like Figure 6 As shown, preferably, the handle 22 and the limiting block 26 are arranged vertically, and the two conducting blocks 19 are arranged in an eight-shaped configuration, showing a staggered arrangement in the up-and-down direction.

[0061] In this embodiment, the vertical layout of the handle 22 and the limiting block 26 design greatly facilitates the staff to rotate the connecting rod 15, so that the limiting block 26 can be quickly and stably embedded in the corresponding matching groove 27, thereby effectively locking the position of the connecting rod 15, enhancing the accuracy of operation and the stability of the device. In addition, by designing the conduction blocks 19 in an upper and lower staggered arrangement, not only the installation space required between the two conduction blocks 19 is significantly reduced, effectively reducing the total volume of the device, but also the connection stability and tacit cooperation between the two are significantly improved, ensuring smoother and more efficient operation of the device.

[0062] Example 3

[0063] like Figure 8 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, a gas separation structure is installed at both ends of the sliding plate 13, and the gas separation structure includes a connecting air pipe 30, and the connecting air pipe 30 is symmetrically fixedly installed at both ends of the sliding plate 13, and circular mounting grooves are provided at both ends of the sliding plate 13, and extrusion rings 31 are slidably connected in the circular mounting grooves at both ends of the sliding plate 13, and the outer rings of the two extrusion rings 31 are sleeved with sealing rings 32, and the inner ring of the extrusion ring 31 is provided with a mounting ring 33, and the mounting ring 33 is fixedly connected to the extrusion ring 31 by a plurality of connecting bolts 34, and the plurality of connecting bolts 34 are distributed in a ring shape on the mounting ring 33, and a gas separation membrane 35 is fixedly installed on the mounting ring 33.

[0064] In this embodiment, when the gas separation membrane 35 needs to be replaced, the staff uses the cooperation of the hydraulic device and the connecting air pipe 30 to extract the hydraulic oil in the circular mounting groove in the sliding plate 13. This operation makes the extrusion ring 31 no longer close to the side wall of the separation tank 7, thereby allowing the sliding plate 13 to translate freely. To ensure the sealing, a sealing ring 32 is installed on the periphery of the extrusion ring 31. As the sliding plate 13 moves, the old gas separation membrane 35 is extracted from the separation tank 7, and the new gas separation membrane is pushed in. Subsequently, the new gas separation membrane is pushed in again through the hydraulic device and the connecting air pipe 30. Hydraulic oil is injected into the circular mounting groove corresponding to the gas separation membrane 35. The pressure of the hydraulic oil makes the extrusion ring 31 fit tightly against the side wall of the separation tank 7, thereby enhancing the sealing effect and ensuring efficient waste gas treatment. For the used gas separation membrane 35, the staff can easily remove the connecting bolts 34 on its outer edge, and then separate the mounting ring 33 from the extrusion ring 31, so as to realize the convenient replacement of the gas separation membrane 35. This alternating working mechanism not only shortens the downtime of the device, allowing it to quickly return to the waste gas treatment process, but also greatly facilitates the maintenance operations of the staff and improves the overall work efficiency.

[0065] It should be noted that the connecting air pipe 30 is connected to the external hydraulic device, and the circular mounting groove of the sliding plate 13 and the extrusion ring 31 are filled with hydraulic oil to cooperate with the hydraulic device to drive the extrusion ring 31 to move and fit with the side wall of the separation tank 7.

[0066] Example 4

[0067] like Fig.10 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, an observation component is fixedly installed on the top of the separation tank 7, and the observation component includes a fixed seat 36, the fixed seat 36 is fixedly installed on the top of the separation tank 7, an industrial camera 37 is fixedly installed on the bottom end of the fixed seat 36, and the end of the industrial camera 37 extends to the interior of the separation tank 7, and a display screen 38 is fixedly installed on the top of the fixed seat 36, and the industrial camera 37 and the display screen 38 are electrically connected.

[0068] In this embodiment, in order to monitor the working status of the gas separation membrane 35 in the separation tank 7 in real time, an industrial camera 37 is installed inside the separation tank 7, which can capture and feedback the detailed status of the gas separation membrane 35 in real time to ensure the timeliness of information. In order to improve the intuitiveness of the operation, the industrial camera 37 is closely connected to the display screen 38. The staff only needs to observe the display screen 38 to understand the real-time usage of the gas separation membrane 35 at a glance. Based on this real-time information, the staff can quickly determine whether the gas separation membrane 35 needs to be replaced, thereby ensuring the continuity and efficiency of the exhaust gas treatment process.

[0069] like Fig.10As shown, in this embodiment, preferably, the industrial camera 37 and the gas separation membrane 35 are arranged at an angle of 110°.

[0070] like Figure 1-Figure 5 As shown, preferably, the industrial camera 37 is installed at a position that forms an angle of 110° with the gas separation membrane 35, ensuring that the industrial camera 37 can capture the details of the gas separation membrane 35 with the widest field of view. Through such a layout, the industrial camera 37 can capture the overall picture of the gas separation membrane 35 and its working status to the greatest extent, and then transmit the real-time image to the display screen 38. The staff only needs to directly observe the picture on the display screen 38 to intuitively evaluate the current status of the gas separation membrane 35, so as to quickly and accurately determine whether replacement operation is needed. This design not only improves the monitoring efficiency, but also greatly facilitates the maintenance and management of the equipment.

[0071] The present invention also provides a treatment method of a multi-stage circulating organic waste gas treatment device, comprising:

[0072] S1, waste gas treatment, transporting the organic waste gas to be treated to the inside of the waste gas impurity removal device 1, cleaning the impurities inside the organic waste gas through the waste gas impurity removal device 1, and then transporting the impurity-free waste gas to the liquid injection screw compressor device 2, and compressing the waste gas through the liquid injection screw compressor device 2;

[0073] S2, gas treatment, the compressed waste gas is transported to the gas-liquid separation device 3, most of the condensed circulating liquid is separated from the waste gas, and then the waste gas enters the condensation device 4 for condensation, a large amount of gas in the waste gas is condensed into liquid and enters the liquid storage tank 5, and the non-condensable waste gas enters the interior of the gas separation component 6;

[0074] S3, gas separation, the non-condensable waste gas is transported to the gas separation component 6, and the gas is separated by the gas separation membrane 35. The non-condensable gas that passes through the gas separation membrane 35 will be enriched and concentrated and then enter the input port of the gas-liquid separation device 3 for gas treatment again. The gas that has not passed through still contains a small amount of polluted waste gas, which will be sent to the terminal equipment for treatment to meet the standards.

[0075] The working principle of the multi-stage circulation organic waste gas treatment device is described in detail below.

[0076] like Figure 1-Figure 5As shown, the organic waste gas to be treated is firstly passed through the waste gas impurity removal device 1 to clean the impurities in the waste gas, and then the impurity-removed waste gas is transported to the inside of the liquid injection screw compressor device 2, and the waste gas is compressed by the liquid injection screw compressor device 2 to increase the pressure to 0.8MPaG, and the compressed waste gas is transported to the gas-liquid separation device 3 to separate most of the condensed circulating liquid from the waste gas, and then the waste gas enters the condensation device 4 for condensation, and a large amount of gas in the waste gas is condensed into liquid and enters the liquid storage tank 5, while the non-condensable waste gas enters the inside of the gas separation component 6 for gas separation, and most of the non-condensable gas passes through the gas separation membrane 35, and enters the input port of the gas-liquid separation device 3 after enrichment and concentration, and the compression and condensation process is carried out again, and the gas that has not passed through still contains a small amount of polluting waste gas, and this part of the gas will enter the terminal equipment through the discharge pipe 10 for standard treatment;

[0077] During the processing, the staff can use the observation component to check the use of the gas separation membrane 35 inside the separation tank 7 in real time. The separation tank 7 is installed with an industrial camera 37, which can capture and feedback the detailed status of the gas separation membrane 35 in real time to ensure the timeliness of the information. In order to improve the intuitiveness of the operation, the industrial camera 37 is closely connected with the display screen 38. The staff only needs to observe the display screen 38 to understand the real-time use of the gas separation membrane 35 at a glance. Based on this real-time information, the staff can quickly determine whether the gas separation membrane 35 needs to be replaced;

[0078] First, the staff uses the hydraulic device and the connecting air pipe 30 to extract the hydraulic oil in the circular mounting groove in the sliding plate 13. This operation makes the extrusion ring 31 no longer close to the side wall of the separation tank 7, thereby allowing the sliding plate 13 to translate freely. Then, the staff will use the handle 22 to rotate the connecting rod 15. As the connecting rod 15 rotates, a limiting component will be activated, thereby releasing the current position restriction of the connecting rod 15. Then, the staff will pull the sliding rod 20 again through the handle 22 to make it slide along the end of the connecting rod 15. The sliding rod 20 drives the conduction block 19 to move synchronously through the connecting seat 21. The movement of the conduction block 19 then prompts the two limiting seats 18 to approach each other. This action releases the original position of the sliding plate 13. The position of the sliding plate 13 is locked. Once the position restriction of the sliding plate 13 is released, the staff can pull the sliding plate 13 through the handle 22 and the connecting rod 15 to make it slide smoothly along the guide rod 12 to the other end of the mounting frame 11. After reaching the specified position, the connecting rod 15 is rotated again by the handle 22 at the other end of the mounting frame 11, and the position of the connecting rod 15 and the sliding plate 13 is re-fixed by the limiting component to ensure that the sliding plate 13 is stable and immovable. At the same time, hydraulic oil is injected into the circular mounting groove corresponding to the new gas separation membrane 35 through the hydraulic device and the connecting air pipe 30 again. The pressure of the hydraulic oil makes the extrusion ring 31 fit tightly against the side wall of the separation tank 7 to enhance the sealing effect. Finally, the staff can easily replace the gas separation structure installed on the sliding plate 13;

[0079] For the used gas separation membrane 35 , the staff can easily remove the connecting bolts 34 on the outer edge thereof, and then separate the mounting ring 33 from the extrusion ring 31 , thereby realizing the convenient replacement of the gas separation membrane 35 .

[0080] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
